To" ALL WHOMIT. MAY coNoERN:

Bc it known that I, OWEN COLLINS, of thelcity, county, und. State of New York, have invented a'. certain new and useful' improvement on Fire-Place Heaters or Furnaces, of which the following is a full, clear, and exact description,reference being had'to the accompanying drawing, forming part'of this specification, and in which- Figures 1 und represent elevations, mainly sectional, at right angles to cach other, of apex-table stove or furnace, or fire-place heater, constructed according to my invention.

Th'cnature of my invention consists in a. novel combination of tubular {irc-bars, through which air is passed, vwith a rear air-chamber inthe base of the furnace communicating with the space or spaces contained within the outer shell or jacket; also inaI novel arrangement of a smoke-decomposing chamber withits inlets and outlets;

likewise in'a combination of sfide and bottom air inlets tothe buse, controlled .by a single 'valv'e for admitting air from different stories or chambers; also in a novel arrangement of draught-tubes, arranged to project into the tire, and controlled by damper-s above; and in a peculiar construction of radiating reflectors and central deilector for the-better distribution of the heat, und serving to prevent lodging or choking, and so return n iattcrcarried up bythe draught or soot deposit back to the tire.

Referring to the aceompanyin g drawing, A represcntsthe fire-place, preferably pf arched form, and B its grate, which may he made torock and tip in the usual manner; C is a door or doors arranged in the buse D v for, when open, to admit u direct curi-eilt of air below or' nearly in line with the fire-bars a, which are made.

tubular to scrvexthc d onble purpose of passing uirfrom the outside throughJthgeni to keep them cool, und of supplying a back chamber, K. E is the ash-pit or pan, and F the lire-door to the {ire-place A., which has c. smokedecomposing chamber, G, outside of it, formed by an arch-shaped jacket, H, and to which chamber, b, are lower and upper inlets, and,c, upper contracted outlets, toone of which, if desired, u. gas-burner may be attached.

Mounted on this jacket Il is a cylinder, I, withixror across which are arranged dempers d, controlled by rods 4or handles c, und serving to close ort-brow open for an upper through-draught, say morefullyor particularly on rstlighting the fire, outlets f, of tubes J, which -descend or run down into the fire, and which, becoming highly heated und establishing tine, quick our-rents, secure a perfect draught.v The sides of the base Decre also formed into outside chambers L, which communicate with .the back chamber K, -and, by openings g-,with a chamber or interior space to a jacket, M, surrounding the smoke-decomposing chamber. These ,side chambers Ilare provided with side apertures Vh and lower openings z', controlled by valvesupr dempers j, whichmay either be' turned to admit nir from a cellar below through the openings z', or from' vthe basement or door on which the furnace stands, through the apertures h. Mounted in n. loose Aand detachable manner on the cylinder o1" cylindrical pro" jection I are reircrsely conical or double-concave reflecting radiators N C),v provided with apertures Ic, and e'ony nected by a. cylinder, P, with which communication is established by an opening or openings, l, und from which the smoke and; escaping gases are passed o by a. pipe, m. The upper radiator 0 is constructed at its centreV with a conical deector, Q, arranged to project downwardly within a cylinder, R, open at its bottom, and provided with lateral apertures n.

A furnace thus constructed, and which may be used as a brick turnace foi` warming, by c suitable shaft or shafts, the various stories of a'building, or which, by extending the jacket M by s. cylinder S,that may bejfurnished with a door and dome, T, may readily be converted into a portable furnace or fire-place heater, will be found both economical in the working and free from escape, along with the heat distributed by it, of noxious gases. To detail some of the advantages of this construction here it may be observed that air entering .by the tubular tire-barsA 'a not only keeps the latter cool, but serves'tosupply, in a partially heated manner, the chum# bers K L and space enclosed by the jacket M, and which, in connection it may be 'with the spaces enclosed by the cylinder S und dome T, from the hot-air chambers of the furnace, while the smoke-decomposing chamber G is well supplied with air to effect ignition. The admission of nir, too, at pleasure, to the chambers L by either the passages h or z', controlled by a Asingle damper on either side, gives increased facility for drawing the supplyY either from the cellar below or Hoor on which the furnace stands, to suit circumstances. The use and ndran-V tages of the tubes J, arranged as described, and controlled by dempers d, have already been referred to. And, lastly, it may be mentioned that not only do the refiecting radiators N O and deector Q serve most effeetually to distribute the heat within the surrounding jacket or space, but by their construction and the arched form of the jacket H, in connection with the cylinder I, soot or other matter carried up by the draught is prevented from accumulating, and readily falls or slides back and is returned to the fire on opening the dampers What I claim as new and useful, and desire to secure by- Letters Patent, is-

l. The arrangement of the tubular grate-bars with relation to the rear and side chambers K L of the base,

communicating therethrough with the space or spaces within the jacket Mysubstantially as specified.

2. The smoke-decomposing chamber G, made to encompass the fire-chamber, and communicating therewith by smoke-passages b, also provided with suitable air inlets and outlets, as herein set forth.

n 3. The combination of the side andvbottom air inlets h and z', to the chambers L of the base. and controlled by dampers or valves J to vary the ingress, essentially asvspecied.. l

4. The draught-tubes J, arranged to descend into there, and controlled by damp'ers d, substantially as shown and described.

5. The reversely conical or concave radiating reflectors O and deilector Q, arranged for operation essentially as represented and described. v-
